I have downloaded NVIDIA-Linux-x86-1.0-8174-pkg1.run from official website. Succesfully installed it. Now it works (glxgears shows ~4000 fps). But refresh rate is 75hz max. Monitor values in xorg.conf correct. I tried to select "nv" driver and it works at 100 hz but no acceleration. With "nvidia" driver - only 75 =(. Anyone solved this problem?
